The reason is that Christoph said his original version of block/raw.c
was meant to be GPLv2-only.  I don't care if the file is BSD or LGPLv2+,
but most of the block layer is BSD, which is why I went for BSD.

It's been a while since I audited the files that would go into
libqemublock, but I remember the only problematic files were block/raw.c
(unlicensed) and block/vdi.c (GPLv2+).  Not having VirtualBox support
wouldn't be a big deal.
